According to ABI Research, Android and iOS remain dominant platforms, with Android in the lead in the smartphone space and iOS dominating the tablet market.

However, developers are also focusing on Windows Phone and BB10. AI analyst Aapo Markkanen believes 45 million Windows Phone devices will be in use by the end of the year, along with up to 20 million BB10 devices. Redmond will also have 5.5 million Windows powered tablet by the end of the year.

Interestingly, up to 40 percent of BB10 apps are merely repackaged Android apps. BlackBerry 10 was launched with about 70,000 apps and many of them were originally developed for Android. According to Intomobile, Blackberry provided developers with great porting tools, allowing them to use their existing code for the new platform.
